It is often criticized that Gibson uses a tone killing "condom" around the trussrod to protect it against the glue when the fretboard is mounted.What about obg ? Anybody who knows if they used this condom as well ?

You didn't know it ? Some people can hear the grass growin...it's almost becoming an industry.You can pay a fortune for some luthiers : they will tell you first that a guitar with this sleeve is not as resonant as one without.They remove the fretboard and the trussrod in the sleeve and install you a historic correct trussrod before they glue a new fretboard on the neck using the same glue made from bones as for the famous bursts.Some luthiers are specialists in bringing your guitar to burst specs.If you buy a Gibson historic for 5000 usd you can loose twice that much if you meet the right luthier...
Anyway I would like to know how japanese Gibsons are build.Just interest.
